Abstract

Objectives

To summarise existing evidence on the impact of temperature on Ross River virus (RRV) and Barmah Forest virus (BFV) notifications across different geographical regions in Australia and to identify knowledge gaps.

Methods

A comprehensive search was conducted across three databases (PubMed, Embase and Scopus) from inception until March 2025. Studies quantitatively assessing the impact of temperature on RRV/ BFV infections were included. Identified studies were screened for eligibility, followed by data extraction and descriptive analysis.

Results

From 406 studies identified, 30 studies were eligible for inclusion. Overall, studies reported a positive association between high temperatures and an increased risk of RRV and BFV notifications in Australia. Geographical variations were observed with maximum temperature being associated with higher notifications of RRV infections in coastal Australia, whileminimum temperature increased the risk of RRV infections in inland regions, and for BFV infections across both regions.

Conclusions

Studies reported an overall positive association between temperature and RRV/BFV notifications, with spatial variations observed in different regions of Australia.

Implications for public health

Given that most studies were carried out in coastal regions, there is a need to undertake further exploration in inland regions in Australia, at a smaller spatial scale to implement tailored prevention strategies.

温度对澳大利亚罗斯河病毒和巴尔玛森林病毒感染的影响：范围综述。

目的：总结温度对澳大利亚不同地理区域罗斯河病毒（RRV）和巴尔马森林病毒（BFV）通报影响的现有证据，并确定知识空白。方法：对三个数据库（PubMed， Embase和Scopus）进行了全面的检索，从成立到2025年3月。包括定量评估温度对RRV/ BFV感染影响的研究。筛选确定的研究，然后进行数据提取和描述性分析。结果：在406项研究中，有30项研究符合纳入条件。总的来说，研究报告了高温与澳大利亚RRV和BFV报告风险增加之间的正相关。观察到地理差异，最高温度与澳大利亚沿海地区RRV感染的较高通报率有关，而最低温度增加了内陆地区RRV感染的风险，以及两个地区的BFV感染。结论：研究报告了温度与RRV/BFV报告之间的总体正相关，在澳大利亚不同地区观察到空间差异。对公共卫生的影响：鉴于大多数研究是在沿海地区进行的，有必要在澳大利亚内陆地区进行进一步的探索，在较小的空间尺度上实施有针对性的预防战略。

期刊介绍： The Australian and New Zealand Journal of Public Health (ANZJPH) is concerned with public health issues. The research reported includes formal epidemiological inquiries into the correlates and causes of diseases and health-related behaviour, analyses of public policy affecting health and disease, and detailed studies of the cultures and social structures within which health and illness exist. The Journal is multidisciplinary and aims to publish methodologically sound research from any of the academic disciplines that constitute public health.
